AUTOMATICALLY-OPERATED COPYHOL'DER ATTACEMENT FOR TYIPEWRI'TEBS.

Application filed November 1, 1921. Serial No. 511,983.

To all whom it may concern.

Be it known that we, SYLVAN RosENTHAL,

a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania; MORRIS SUBBER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania; and HARRY A. RosENTHAL, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Automatically-Operated Copyholder Attachment for Typewriters, of which the following is a specification.

Our invention consists of a novel construction of an automatically operated copy holder attachment for typewriters, which is adapted to be readily installed upon any existing typewriter of any standard or conventional type, and comprises novel means whereby the manual shifting of the typewriter carriage of ordinary construction effects an intermittent or step by step rotation of feed rollers, between which the copy passes, whereby the copy or manuscript to be transcribed upon the typewriter is auto matically propelled or caused to move upwardly to the desired extent each time the carriage is shifted, without requiring any attention on the part of the operator, so that an uncopied portion of said copy is at all times visible to the operator.

It further consists of novel tripping or actuating means common to the typewriter carriage and to thenovel actuating mechanism of our invention, whereby the feed rollers through which the copy is propelled are actuated by novel pawl and ratchet mechanism during each lateral shifting of the carriage.

It further consists of a novel construction of framework adapted to be readily attached to an existing typewriter and feed rollers mounted in the upper portion thereof between which the copy passes and by which feed rolls said copy is propelled by a novel pawl and ratchet mechanism actuated by each lateral shift of, the typewriter carriage.

It further consists of a novel construction of framework adapted to be attached to any existing typewriter, a pair of feed rollers mounted in the upper portion thereof, and

suitable guiding and propelling devices for retaining in position and actuating the manuscript to be copied.

It further consists of other novel features.

In carrying out our invention, which is tee ' manner. The parts constituting our invention are delineated in full lines and coniprise the dog 3, which, is composed of the body portion 4: havingthe eye or seat 5 in the upper portion thereof, which is adapted to be slid upon and secured to the rod 6 or" the typewriter carriage 2. The dog 3 is held in position upon the rod 6 by means of a set'screw 7 or other equivalent device, and at its lower portion it is provided with a projecting pin 8 which is adapted when the carriage approaches its extreme right hand position to engage thependant arm 9, which is secured by the pin or bolt 10 to the plate 11 which is fast to one end of the rock shaft 12, having the squared end 13 seen in Figure 6, the latter being mounted in a suitable bearing or bracket 12 and having secured to its other end the bar 13,: it

being apparent that the parts 11, operate in unlson as aunit.

The pendant arm 9 can oscillate freely on 12 and 13 the pin 10, and has at its upper right hand edge the recess 10*, theinner wall of which engages the pin 11 which is'tast to the plate 11, so that it will be apparent that when the arm is actuated into the position seen dotted in Figure 5, the contact of the inner wall of the recess 1O with the pin 11 will actuate the latter, the plate 11, the shaft 12, and

the slotted bar 13.

The bar 13 has a slot 14 therein, through Y. which passes the shouldered screw 15, which engages the lower end 16 oi the connection or clevis 17, the upper end of the latter having the lower end 18 01 the rod 19 in threaded or adjustable engagement therewith, theupper end of said rod 19 being in threaded engagement with the head 20, winch s pivotally attached at 21%. to the bar 22 wh1ch is in sliding contact with the upper portion 23 of the framework or housing of the device. The shouldered screw has the round portion 15*, see Figure 7, and the threaded portion 16*, which engages the nut 17*, which has the squared portion 13*, which engages the slot 1 1.

The bar 22 has the upper and lower slots 2eand25 therein, through which pass the guide screws 26, whereby said bar 22 is 210 curately and exactly guided in a vertical The the pawl 28, which depends from itsipivotal support 27 and against which bears the free end or" the spring 29, whereby the lower end of the pawl is pressed into engagement with the teeth ofthe ratchet wheel 30. Theispring 3 1 has ts upper end attached to the trainenaeneea pivoted above the ratchet wheel 30 and is adapted to engage the ratchet teeth thereof at all times, as will'be understood from Figure a, by reason of the spring 33. which causes the free end of said locking pawl 32 to always engage said ratchet 30. The ratchet wheel 30 is fast a shaft 34 upon which the feed roller 35 is mounted, said teed roller being juxtaposed to or in contact with the upper feed roller 36, between which feed rollers the copy or transcript 37 to be copied passes. The upper feed roller 36 has its journals 36 projecting beyond the frame-work 23 and provided with the ten sion devices or resilient means 37 bearing on said journals, so that the free rotation of the upper feed roll 36 is retarded.

The manuscript 3?, as will be apparent trom Figure 3, is inserted in the device so as to pass over the abutment v38. thence to the rear of the guide plate39, which has the rectangular or other sight opening 40 therein, said manuscript then passing over the lower feed roll .35 and below the upper feed roll 36. so that it will be apparent that as an intermittent up and down movement is imparted to the rod 19, the bar 22 wil1 simultaneously be given a similar up and downmovement and the reciprocations of said bar will actuate the pawl 28 a distance equal to one tooth of the ratchet wheel 30,

said pawl being pulled downwardly by the 7 spring 31 so that during each lateral shift of the typewriter carriage 2, through the medium of the dog 3, pin 8. arm Qand the connections therefrom to. the rod 19,, the ratchet wheel. 30 will be given a rotation to the extent of one tooth, thereby propelling the manuscript or copy 37 upwardly an eX- tent equal to one tooth each time that the typewriter carriage 2 is manually shiftedv to its extreme right hand position. I

he rod 19 can be adjusted by means of its upper and lowerthreaded connections. so that the throwv of the pawl 28 will equal two or more of the teeth of the ratchet wheel 30. r i V It will be apparent that the upper opera.- tive parts of our device. comprising .the upper andlowe-r rollers 36 and 35, the pawl and ratchet mechanism and their adjuncts,

can be supported with. respectto any con- 'ventional or standard typewriter in any suitable manner or in any desired form of housing, and in the present instance, we have shown one form othousing which can be readily attached to existing typewriters, the same comprising the two uprights i1,

which are provided at their lower ends with the feet or lateral extensions 4:2 which can be conveniently attached to any suitable portion of the typewriter, said uprights 41 be ing braced by the inclined or diagonal bars 43, whose lower ends or feet or can be readily attached to any conventional part of the typewriter shown in Figure l, as is evident.

The upper transverse plate 39 having the opening 10 therein through which the ter to be copied is visible, is secured in any suitable manner to the two uprights d1.

It will be understood that there are two or the upper plates 23 in which the feed rollers and the pawl and ratchet mechanism. are supported, and while we have shown the preferred manner of mounting and actuatmg our novel device, it will of course be understood that slight changes may be made therein without departing from the spirit of our invention.

In case it should be desired to manually manipulate the copy 37 forwardly or backwardly. this can be done by rotating the knob 45, which is mounted on the extension at from the shaft 34, so that the manual rotation of the knob or finger piece 45 will effect the rotation of the feed rolls 85 and 36 to the desired extent and the desired actuation of the copy 37 between them, so that the position of said copy can be manually adjusted at any time, according to requirements.

In Figures 1, 2 and 3, we have shown laterally extending brackets 47, which are attached to a suitable portion of the framework or housing, each of which carries the upright spindle as on which the spools as are mounted, the top of each of said spools being provided with the handle 50 and said spools having a band 51 mounted thereon, which may contain written or other desired matter for the operator, which can be positioued, as may be desired.

The housing or framework of our invention is also preferably provided with a curved guide or guard 52, whereby the sheet containing the typewritten matter is properly directed as it is fed upwardly out of the typewriter carriage 2.

It will be apparent that the various elements embodying our invention can be readily manufactured at minimum expense and can be installed upon a standard or conventional typewriter by any person of average intelligence, and the same will not readily get out of order.

We have deemed it unnecessary to describe the construction of the typewriter and carriage shown in dotted lines, as our invention is applicable to any standard or conventional typewriter having a lateral shitting carriage of the character commonly in vogue,

It will be apparent that the dog 3 may be connected to any desired portion ofthe carriage 2, but for convenience, we secure the same to the rod 6, as this construction is found to be eiiicicnt and efiective in practice.

It will be apparent that by loosening the nut 17 and shiftin the m mber 15 in the slot 14 (see Figures 2. 7 and 8) the extent of travel of the rod 19 can be varied, and by adjusting the rod in the heads 17 and 20, the properadjustment of the coactinc; parts can be effected.

The plate 20 may be made oi any suitable material as metal, cardboard, fibre or the like and is preferably dropped downwardly into the position. by the guards or wires 53, as seen in Figure 1.

It will now be apparent that we have devised a. novel and useful automatically operated copy holder attachment for typewriters which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while we have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that such embodiment is susceptibleof modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

l. The combination of a typewriter carriage having a dog thereon, a housing having a pendant arm pivotally supported thereon, a plate from which said arm depends. a pin projecting from said plate and engaging the walls of a slot in said arm, a rock shafton which said plate is mounted, a bar in engagementwith said rock shaft and having a slottherein, an upright actusting rod having its ends threaded and its lower threaded end mounted in a head adjustably supported in said slot, a head attached to the upper threaded end of said rod. a bar pivotallyattached to said upper head, guiding devices for said bar, a pawl on said bar, a spring holdino' said bar and pawl in proper position, a pair of feed rollers, a ratchet wheel mounted on one of said feed rollers, and a locking pawl for said ratchet wheel.
